Abstract
Aspects of the methods according to the present disclosure relate to the fabrication of refastenable pant diapers wherein discrete chassis are advanced in a machine direction such that the lateral axis is parallel with the machine direction. First side panels are then refastenably connected with the first waist region, and second side panels are permanently connected the second waist regions of the discrete chassis. The methods disclosed herein connect chassis with discrete lengths of side panel material and/or connection zone material, and forms a continuous web of articles formed by intermittently spaced chassis and intermittently spaced side panels bridging the gap between the intermittently spaced chassis. The chassis are then folded in the cross direction parallel to a lateral centerline and the first and second side panels are subsequently bonded together. The article is then subjected to knife cut adjacent the bonded regions to create discrete, pre-fastened refastenable pant diapers.
